Amazon Aurora DSQL FAQs

General

Aurora DSQL is a serverless distributed SQL database designed to scale to meet any workload demand with up to 99.999% multi-Region availability and no infrastructure management. It is PostgreSQL-compatible and provides an easy-to-use developer experience. With Aurora DSQL, you only pay for what you use.

Aurora DSQL is optimized for transactional (OLTP) workloads.

In only a few steps in the Aurora DSQL console, you can create a new database. For more details, go to the user guide.

Aurora DSQL is currently available in preview in the following AWS Regions: US East (N. Virginia), US East (Ohio), and US West (Oregon). US West (Oregon) is only available as the witness Region for multi-Region configurations.

The Aurora DSQL distributed architecture is designed to automatically scale each component—compute, commit, and storage—independently to meet any workload demand and with no single leader. This reduces dependencies and allows reads and writes to dynamically scale up/down and out/in to virtually no limit. It also means Aurora DSQL can quickly deploy each component with no impact on performance.

Aurora DSQL removes the need to upgrade or migrate your database to larger instances. It automatically scales out to virtually no limit to meet any workload demand.

No, Aurora DSQL is a new database option under Amazon Aurora. Aurora PostgreSQL and Aurora MySQL provide the choice of add-on features, such as Aurora Serverless v2, Aurora Global Database, and Aurora Limitless Database, to enhance the open source engines. With Aurora DSQL, serverless, high-availability, and scaling features come built in.

High availability

Highest availability means Aurora DSQL provides up to 99.99% single-Region and 99.999% multi-Region availability to help ensure your applications are always available.

Active-active refers to the high-availability features of Aurora DSQL that provide up to 99.999% multi-Region availability. With active-active high availability, Aurora DSQL provides a fully managed, redundant Regional endpoint per cluster. This means that your applications can continue to read and write with strong consistency, even in the rare case an application is unable to connect to a multi-Region cluster endpoint.

With Aurora DSQL, there are no primary or secondary nodes to configure and no failover procedures to manage. It has built-in fault tolerance, featuring automatic load balancing that routes your requests to healthy components and automated self-healing to correct component-level failures.

Easy to use

Aurora DSQL uses AWS Identity and Access Management (IAM) policies to define permissions and user roles.

This means Aurora DSQL supports many of the commonly used PostgreSQL queries and popular features. It will return identical query results for all supported features, provide identical behavior for most supported features, and support many popular PG drivers and tools with minor configuration changes. Visit the Aurora DSQL PostgreSQL-compatible page for more details.
